2pcs/lot LoRa1278 - 4Km 100mW 433MHz High sensitivity sx1278 chip Lora module ultra long range RF Wireless Transceiver Module

aeProduct.getSubject()

LoRa1278 adopts Semtech RF transceiver chip SX1278, which adopts LoRa TM Spread Spectrum modulation frequency hopping technique. The features of long distance and high sensitivity (-139 dBm) make this module perform better than FSK and GFSK module. Multi-signal won\'t affect each other even in crowd frequency environment; it comes with strong anti-interference performance.

  • Frequency Range: 433MHz/470MHz (Customizable 137-1020 MHZ)
  • Sensitivity up to -139 dBm
  • Maximum output power: 20dBm
  • 10.3mA@receiver mode
  • Sleep current <200nA
  • Data transfer rate:@FSK,1.2-300kbps
  • @Lora TM,0.018-37.5kbps
  • Lora TM ,FSK,GFSK and OOK Modulation mode
  • 1.8-3.7 V Power supply
  • 127 dB Dynamic Range RSSI
  • Packet engine up to 256 bytes with CRC
  • Operating Temperature Range:-40 ~ + 85 °C
  • Built-in temperature sensor and low battery indicator
  • Excellent blocking immunity
